A Retrospective Longitudinal Study Regarding The Dental Anomalies Of Position With Eruptive Etiology.

Objective: Given the high frequency of dental anomalies of position and the lack of preventive measures of surveillance and monitoring of the eruption of permanent teeth, the aim of this study is to evaluate the frequency of dental anomalies of position in children. Material and methods: We conducted a retrospective longitudinal study in the 2006-2012 period. Data were collected from the medical records and orthopantomography x-rays of 408 patients (230 female and 178 male) who presented to the Pedodontics-Orthodontics Clinic in Tîrgu Mureș. After applying the exclusion criteria, 77 patients remained in the study. Results: From the 77 patients, 57 had dental inclusions, 15 presented ectopic teeth, dental rotations have been observed in 2 patients, and midline diastema in 5 patients. Regarding sex distribution, there was a higher frequency of dental inclusions in women (39) than men (38). The frequency of dental inclusions, regarding dental groups, in a descending order was: maxillary canine, mandibular second premolar, mandibular canine, maxillary second premolar, mandibular first premolar, maxillary first premolar, maxillary lateral incisor, maxillary central incisor and maxillary and mandibular first molars. The frequency of dental inclusions in the dental support area had the highest rate in the 12-14 years age group. Conclusions: From all the studied dental anomalies, dental inclusions presented the highest frequency. Regarding the dental support area, most cases of dental inclusion were observed in the 12-14 years age group. [ABSTRACT FROM AUTHOR]
